This lizard varies extremely in the degree of elongation of the 

 snout, in the scutellation of the head, in the number of rows of 

 scales, and in colour ; but I am satisfied that the several forms 

 hitherto described should be united into one species, which I 

 divide into numerous varieties of colouration." — Boulenger.
